These records are the official minutes of the Board. They are compiled at the direction of the Secretary of the Smithsonian, who is also secretary to the Board, after
approval by the Regents' Executive Committee and by the Regents themselves. The minutes are edited, not a verbatim account of proceedings. For reasons unknown, there are no
manuscript minutes for the period from 1857 through 1890; and researchers must rely on printed minutes published in the Annual Report of the Smithsonian Institution instead.
Minutes are transferred regularly from the Secretary's Office to the Archives. Minutes less than 15 years old are closed to researchers. Indexes exist for the period from
1907 to 1946 and can be useful.
